目的探讨超声心动图对双腔左心室的诊断方法及其临床应用价值。方法经超声心动图诊断双腔左心室患者9例,总结分析其临床资料和超声特征。结果 9例患者均确诊双腔左心室,其中7例主、副腔为上下排列,2例为左右排列。2例副腔室壁变薄、运动减低,1例副腔室间隔偏厚。2例左室收缩功能减低。1例主、副腔间交通口梗阻。9例均不合并其他心血管畸形。结论双腔左心室是一种罕见的心血管畸形,具有典型的超声心动图表现,检查时需与左室憩室、左室室壁瘤及左室心肌致密化不全相鉴别。超声心动图在双腔左心室的诊断、治疗及预后评估等方面有较大的临床应用价值。
Objective To investigate the diagnostic method and clinical value of echocardiography in the diagnosis of double-chamber left ventricle. Methods Nine patients with double-chamber left ventricular were diagnosed by echocardiography. The clinical data and characteristics of ultrasound were analyzed. Results All the 9 patients were diagnosed as double-chamber left ventricle. Among them, 7 cases had the main and secondary cavities arranged up and down and 2 left and right arranged. 2 cases of accessory wall thinning, decreased motion, 1 case of accessory ventricular septum thicker. 2 cases of left ventricular systolic function reduced. 1 case of main, parasternal traffic port obstruction. None of the 9 patients had any other cardiovascular malformations. Conclusions Double chamber left ventricle is a rare cardiovascular malformation with typical echocardiographic findings. It needs to be differentiated from the left ventricular diverticula, left ventricular aneurysm and left ventricular myocardium. Echocardiography has a great clinical value in the diagnosis, treatment and prognosis evaluation of double-chamber left ventricle.
